System B \[ \begin{array}{r} -x-5 y-5=0 \\ x-5 y=5 \end{array} \]

Step 1 ：The system of equations is a linear system with two variables, x and y.

Step 2 ：The first step to solve this system is to add the two equations together. This will eliminate one of the variables, allowing us to solve for the other.

Step 3 ：After finding the value of one variable, we can substitute it into one of the original equations to find the value of the other variable.

Step 4 ：The solution to the system of equations is \( \boxed{x = 0, y = -1} \).
